研究了时序模糊软集的群决策问题，针对实际问题中模糊软集的信息随时间动态变化对最终决策的影响不同，将这类影响量化为时间权重，根据各对象保持前一时刻状态的能力不同，造成对象集整体在不同时刻状态有所差异，得到权重值；并利用集成思想，通过时序模糊几何加权平均算子将时序模糊软集集成为综合模糊软集；再利用水平软集等工具计算各对象的机会值，得出最优决策。最后，给出具体的时序模糊软集的群决策步骤，并通过实例验证了决策方法的合理性及可行性。

Group decision-making problems based on times-series fuzzy soft set have been investiga-ted. For the situation that fuzzy soft sets information dynamic change as time has different effect on fi-nal decision,there have been quantified these effects to time weights and obtained them by optimiza-tion programming model. With aggregating thought,the time-series fuzzy soft sets have been aggrega-ted into collective fuzzy soft by time-series fuzzy weighted geometric average operator. The optimal de-cision can be obtained by calculating choice value of objects with the level soft set. Finally,the group decision making approach based on time-series fuzzy soft sets has been proposed and a practical exam-ple has been analyzed to verify the reasonability and feasibility of the approach.
